Pteridology, Gymnosperms and Palaeobotany (Bscbo-103) Like the pteridophytes, many taxa are now extinct, relics of a much larger group. Gymnosperms have naked seeds, which results in the lack of an ovary as the seeds are not contained in fruit. Secondary growth is present in gymnosperms and angiosperms (dicots).
